PLASTIC COMPOSITION.

srecrrl'cano'u forming part of Letters Patent No. 775,631, dated November 22, 1904.-

Application filed August 20, 1904. Serial No. 221,557. '(NO specimens.)

To all whom it puny concern.-

Be it known that 1, ROBERT MCCARREL, a citizen of the United States, residing at J acksonville, in the county of Duval and State of 5 Florida, have invented new and useful improvements in Plastic Composition, of which the following is a specification.

My invention relates to a composition for art' ialitone and stimco; and it consjs, ts in 10 t e followmgingredients: P ement, hydreulielime, ground coral, fine sand, and reundgmnite.

' In carrying out my invention 1 take hydraulic lime tvgo parts, (and thoroughly R113 5 the same with am 1 san two parts,.groun coral two parts, and ground ranite oneia part. This mixture is left in a cap for about twenty-four hours toallow the lime to cool. Portland cement, one part, is then addedfiafter which the whole mixture is run through a revolving sieve and the ingredients thoroughly mixed. After this step'the mixture is dampened just enough to start it to set, and it is then tamped in molds of any desired 5 size or shape.

This composition produces a strong and durable artificial stone, and it can also be used for stucco. The coral gives the composition the texture and appearance of oolitic limestone. it also closes the pores and solidifies the composition, so that it can be cut, carved, and otherwise worked, and also split with wedges the same as natural stone, and it keeps the same 'color and texture on chiseled parts as on molded parts.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. As a composition of matter, hydraulic lime, ground coral, sand, ground granite and Portland cement combined in about the pro- I portions set forth.
